@Sanjuro - The guy is a 4w3. He says so at the beginning of his e3 video. Btw did he remind anyone else of Dr. Brian Cox?
I thought the video was all right but I didn't finish it and I'm not sure that I should bother. A lot of the acting seemed a little superfluous, he could have sit still and explained without risking alienation. I suspect though that its an important area to him and part of the whole "acting" is the expression of something he really cares about/really enthusiastic about.
In regards to the above - I don't mind feeling calm (usually anyway. It can cause problems if I need to enthuse pure emotion into a creative outlet). I find you can still feel the emotion that exists in a state of calm and can still reflect, fantasise and dream whilst in this state (without the risk of intrustive thought). It is especially helpful if it involves a character of mine reflecting upon their situation or their world - especially if the place in question is a place with a great city which has now fallen silent e.g. the ruins of an ancient city.
The void aka when you feel "nothing" is the part I dislike. That point where you feel little and cannot dream or reflect. It's some food for thought if such a state is actually the embodiment of the meditative calm found in Eastern spirituality.
